According to this article, screen time doesn’t matter; rather, it’s whether your phone is a needy, attention-sucking vampire that determines if it’s time to limit its control on your life. The main metric tracked by screen time apps is deemed deceptive, as it doesn’t take into account the quality of the time spent staring at your screens. Therefore, evaluating the quality, not quantity, of time spent with your phone is the key to improving the relationship with technology. Apps that do their job and politely step aside are good; however, anything not honoring your time and attention is disrespecting you, regardless of the duration of use.
